An emitter bias Dual Input Balanced Output differential amplifier has VCC=20v, β=100, VBE=0.7v, RE=1.3kΩ. Find IE

(a) 7.42mA

(b) 9.8mA

(c) 10mA

(d) 8.6mA

The question was asked by my school teacher while I was bunking the class.

Query is from Differential Amplifier and Circuit Configuration topic in division Operational Amplifier of Linear Integrated Circuits

Accurate choice is (a) 7.42mA

Delve into insight with: Emitter current can be found out by substituting the values in the equation,

⇒ IE = (VEE-VBE)/(2RE)  = (20v-07v)/(2×1.3kΩ) = 7.42mA.
